claimed.

In the accompanying drawings, Figure 1 is an isometric view of the lowerpart of the upper sash and the upper part of the lower sash of a windowwith my improved lock applied to the meeting-rails of the window; Fig.2, a vertical transverse section of the meeting-rails and adjacent partsof a window, showing my improvement in side elevation, the window beinglocked in Figs. 1 and 2; Fig. 3, like Fig. 2, except that the window isrepresented as being opened, but not opened sufficiently to free theswinging bolt; Fig. 4:, a vertical section of parts of two mectingrailsand my device, also in section, the dotted lines showing the position ofthe thumb-lever and swinging bolt when the window is about to be opened.

A A represent the upper and lower sashes of a window ofcommonconstruction, such as is opened by silding either or both of the sashesvertically. To the lower rail or meetipg-rail, a, of the upper sash issecured the lock case or stand B, the same consisting of a plate, 1),provided with two vertical standards, b b, between which standardsswings on the pivot c the bolt 0, said pivot passing horizontallythrough said standards and being supported thereby. The back or outerside of the bolt 0 is recessed at 0, below the pivot c, to receive oneend of aspiral spring, D, the other end of said spring surrounding andbeing held in place by a stud, b cast or otherwise secured to the insideof the vertical back 6 of the lockcase B, the spring D normally throwingthe lower end of the bolt forward over the upper rail, a, of the lowersash when the window is closed, and preventing the window from beingopened. To open the window, the lower end of the bolt must be pushedback out of the way and the lower sash raised or the upper sash lowereduntil the lower end of the bolt is below the top of the lower sash. Whenthe window is being closed, the bolt is swung back by contact with themeeting-rail a of the lower sash, and springs forward over said meetingrail a as soon as the window is closed,without requiring anymanipulation of the lockthat is, closing the window automatically looksit.

To lessen the wear of the upper rail of the lower sash, said rail isprotected by a strike or plate, E, secured by screws 0 e to the top ofsaid rail, the rear upper edge of the strike being beveled at c to fitthe bottom of the bolt 0. The rear of the strike projects over themeeting-rail of the upper 'sash, and is grooved on its under surface ate", and the upper sun face of the front part of the plate b is alsocorrespondingly grooved at If, so that the strike and the plate b hookinto each other and render it impossible to thrust a knife or thin sheetof metal between the strike and the plate b from the outside or back ofthe window. The parts of the grooves c b which come in contact with eachotherthat is, the front side of the groove 7 5 b and the back side ofthe groove 6 2 ll6 outwardly inclined to draw the sashes together andprevent the air and dust from entering the room between the upper andlower sashes. On another horizontal pivot, f, supported in the samemanner as and parallel with the pivot 0, turns a thumb-lever, F,whichnormally occupies the position shown by the full lines in Fig. 4, itsfree end or handle f being raised and a stop, f,whichin the drawings ismerely 8 5 a flat surface, resting upon the top of the back b of thelockcase and limiting the motion of said lever. Against the front side,f of the lever F, above the pivot f, normally rests thebackwardly-projecting upper end, 0*, of the bolt 0, the lever thusacting as a stop to limit the forward motion of the lower end of saidbolt.

0bviously,when the upper end of the lever F is bent forward down intothe position shown in Fig. 3 and by dotted lines in Fig. 4, the upperend of the bolt 0 will be thrown forward, and the lower end of the boltwill be drawn backward in such a manner as to clear the rear edge of thestrike E in raising the 00 window, and in this position the bolt may beheld by the catch-surface f of the lever F,

eet1on,c.

said catchsurface being arranged between the top of the front side, f,and the handle f being pressed down below the upper end or pro-Hence,when it is desired to open the window, it is only necessary todepress the upper end of the lever F into the position shown in Fig. 3,and the window may be opened by moving either sash in the usual manner;but the act of opening the window brings the strike and the upper end ofthe lever into contact and lifts the lever back to its normal position,releasing the bolt, the lower end of which springs forward to be inreadiness again to lock the window.

The lock above described may be applied to a swinging window or door, inwhich case, if the door opens inward, the lock-case and its containedparts would be applied to the jamb and the strike would be secured tothe lockstile of the door. If the door opens outward, the position ofthe lock-case and strike would be reversed. The device above describedpre vents the rattling of the sashes by drawing them together, as abovestated, and allows both hands to be used in raising heavy windows, (thewindows being first unlocked, as

above described,) and makes it positively certain that a closed windowis locked.

I claim as my invention- The combination of the case, the lever piv- 3ooted therein and provided with a handle, the bolt pivoted in said casein front of said lever, the spring pressing the lower end. of said boltforward -and. normally causing it to project out of said case, andholding the upper end of said bolt against the front side of said leverabove the pivot of said lever, said lever being provided with acatch-surface arranged at the top of said front side and between saidfront side and said handle, and adapted, when said handle is drawnforward, to engage the upper end of said bolt and to prevent the forwardmovement of the lower end of said bolt, as and for the purposespecified.

In witness whereof I have signed this speci- 5 fication, this 19th dayof September, A..D. 1887, before two subscribing witnesses.
